Problem

Can you solve this algorithmic problem using an optimized approach?

Implement min_subarray_len(nums, target) to return the minimum length of a contiguous subarray whose sum is at least target. All values in nums are positive integers; return 0 if no qualifying subarray exists.

Input: a list of positive integers and a positive integer target. Output: an integer representing the minimum qualifying length.

Constraints

1 <= nums.length <= 1000
1 <= nums[i] <= 100000
1 <= target <= 1000000000

Function Signature

def min_subarray_len(nums, target):
